Purpose – This paper aims to identify and examine valid project termination reasons and the rebidding strategies of road construction project. Rebidding strategies is one of the measures to restructure terminated/troubled road construction project. Design/methodology/approach – An instrument which comprised 82 items entitled “Project Termination and Rebidding Strategies in Road Construction Projects in Nigeria” (PTRS) was developed to evaluate 60 randomly sampled road projects using qualified project/site managers and engineers as project respondents for the purpose of securing valid information on the terminated and rebid road construction projects. Mean, standard deviation and factor analysis shall be used as analytical tools in identifying valid termination reasons and rebidding strategies and as well as the relationship between them through regression analysis. Findings – The paper’s findings revealed major project termination reasons and rebidding strategies. It further indicated significant relationship between variables which constitutes project termination reasons and rebidding strategies through regression analysis. Practical implications – The outcome of the paper could be of immense benefits during the procurement phase of public project, especially regarding road construction. Stakeholders involved in the road procurement should seek relevant information concerning the road project reprocurement from the expert prior to contractual obligations. Originality/value – Major challenges confronting the road construction project involve inappropriate procurement practices which frequently culminate into late deliveries of project. Rebidding strategies serve as a model through which cost, time and quality needs of the project client can be reassured in restructuring a terminated/troubled project.

Optimal Movement

Purpose This study aims to assist the project manager in minimising the material logistics cost of road project by planning the optimal movement of aggregate across three stages of supply chain: sourcing, processing and distribution. Design/methodology/approach The paper conceptualises the raw material consumption in a road project as a logistics network distribution problem. A linear programming (LP) formulation is constructed with appropriate decision variables by integrating the three stages of material movement. The series of LP scenarios are solved using an LP solver to decide the optimal movement of the aggregate to be consumed in different layers of road segments. Findings The results obtained from the model show that planning material logistics of an entire road project using optimisation provides substantial saving in logistics costs than using common sense. Further, the magnitude of cost saving improves as the complexity of the model increases in term of enormous feasible options. Practical implications The model shown in this paper may serve as a basis for planning the logistics of raw materials consumed in the road projects. The small improvement in material flows by optimising supply chain shows sensible cost benefit to the project manager and hence control and monitor the overall cost and activities of the project. The output of the model is also expected to help the project team as an input in the decision-making processes such as appropriate material sourcing contract, capacity assessment of material processing facility and transportation planning. Originality/value While the optimisation models are widely used and popular among the many industrial applications, this research shows distinct application of such a model in managing the logistics of the road construction project.

Purpose This paper aims to quantify the impact of craft worker shortage on construction project safety performance. Design/methodology/approach A database of 50 North American construction projects completed between 2001 and 2014 was compiled by taking information from a research project survey and the Construction Industry Institute Benchmarking and Metrics Database. The t-test and Mann-Whitney test were used to determine whether there was a significant difference in construction project safety performance on projects with craft worker recruiting difficulty. Poisson regression analysis was then used to examine the relationship between craft worker recruiting difficulty and Occupational Safety and Health Administration Total Number of Recordable Incident Cases per 200,000 Actual Direct Work Hours (TRIR) on construction projects. Findings The result showed that the TRIR distribution of a group of projects that reported craft worker recruiting difficulty tended to be higher than the TRIR distribution of a group of projects with no craft worker recruiting difficulty (p-value = 0.004). Moreover, the average TRIR of the projects that reported craft worker recruiting difficulty was more than two times the average TRIR of projects that experienced no craft recruiting difficulty (p-value = 0.035). Furthermore, the Poisson regression analysis demonstrated that there was a positive exponential relationship between craft worker recruiting difficulty and TRIR in construction projects (p-value = 0.004). Research limitations/implications The projects used to construct the database are heavily weighted towards industrial construction. Practical implications There have been significant long-term gains in construction safety within the USA. However, if recent craft shortages continue, the quantitative analyses presented herein indicate a strong possibility that more safety incidents will occur unless the shortages are reversed. Innovative construction means and methods should be developed and adopted to work in a safe manner with a less qualified workforce. Originality/value The Poisson regression model is the first model that quantifiably links project craft worker availability to construction project safety performance.

Practical Model

Purpose Road construction projects are one of the strategic industries in each country and their construction and development requires spending huge funds. Regarding the increased demand and resource constraints; a technique which reduces costs by maintaining and improving the functioning is of great importance for the authorities of each country. Value engineering is a comprehensive and coherent means based on innovation and team work which, in addition to maintaining the quality and improving the project function, reduces its cost and is not limited to the design and construction phase; however, it includes exploitation and maintenance as well. This study aims to present a practical model for the implementation and application of value engineering process in a construction project located in a special region (in terms of tourism, positioning in an economic growth path, and the East-West strategic axis of the region). In this regard, after reviewing the advisor's design, considering the interests of the project stakeholders, reviewing design criteria and assessment methods and with the use of value engineering techniques, a new option was presented which led to a significant reduction in costs and time and an increase of quality, safety, and environmental factors. Finally, including initial costs, repair, maintenance, income and expenses, the relative value index of this option, compared to the advisor's option, increased from 0.9 to 3.5. Based on the increased need for development of roads in the country, exploiting this model in similar projects can significantly improve the project value and the effectiveness of investments. Design/methodology/approach This research project was selected with regard to the extremely high credit of the project and its potential in terms of Value Engineering implementation. In this study, technical and financial information were first collected after forming a value engineering team including a value engineering expert who was responsible for coordinating the work, some representatives of the employer, designer, executor, and budget estimator. In functional analysis phase with the use of FAST graph, advantageous, costly, and risky functions were identified. In the creativity phase, ideas related to selected functions were created and investigated and developed in the evaluation phase. Finally, calculating the value index, two variants with higher value index than the baseline plan, were proposed and implemented. Findings Since the determining criteria of designing and implementation of road construction projects including increased safety, reduced travel time, user satisfaction, ease of implementation, cost of construction and maintenance and so on are almost similar in most projects, using this study results and implementing its practical framework in other construction projects can be beneficial. These parameters lead to an increase in quality, value, and safety of the project. With regard to done steps and resulted incomes, this essay can be known as a practical and theoretical model to promote the value of crucial projects especially in developing countries. Research limitations/implications Sanandaj-Hamedan road with the length 176km connects central provinces of Iran. This study is regarding the first part of this route. Based on the specific topography of the region and the existing road limitations, selecting a good variance with all the features of an ideal road from geometric, economic, and safety aspects is a difficult task. Originality/value Employers and project sponsors are always looking for products with greater value and lower cost; therefore, present a practical model for the implementation and application of value engineering process in a construction project and providing a similar work experience can encourage the use of value engineering techniques and significantly improve the project value and the effectiveness of investments.

Purpose: Major road construction projects across Kilifi County have experienced delays in delivery due to a majority of contractors, both local firms and government agencies, failing to adhere to agreed-upon completion dates.it is in the backdrop of these problems that influenced the researcher to establish the influence of time management on the implementation of road projects in Kilifi County. The main purpose of this study was to examine the influence of time management on the implementation’s road constructions projects in Kilifi County.Methodology: The study adopted cross sectional research design and collect data using questionnaires from 120 engineers/project managers, supervisors/inspectors and technicians/foremen from 12 organizations including five construction companies involved in urban road construction projects in Kilifi County, five service providers whose utility facilities run along road construction corridors in Kilifi County, and two state corporations charged with the management of road construction in Kenya. Data was analysed using both descriptive and inferential statistics with the help of IBM SPSS Statistics. Descriptive analysis involved the use of frequencies, percentages, mean and standard deviation in order to summarize the results of the various study variables. Inferential analysis involved the application of Pearson correlation and regression analysis to determine the nature of relationship between time management and implementation of road projects in Kilifi County.Results: The study found out that activity sequencing positively and significantly affects road constructions projects in Kilifi County (r = 0.688, P=0.000 < 0.01). The study further determined that a unit improvement in activity sequencing would lead significantly lead to improvement in road project implementation (β = 0.127, t = 2.037, P=0.044 <0.05). It was also determined that resource estimation positively and significantly affects implementation of road constructions projects in Kilifi County (r = 0.721, P = 0.002 < 0.01). the analysis also showed that a unit improvement in resource estimation would lead to a unit improvement in road project implementation (β = 0.218, t = 2.741, P = 0.005<0.05). The study also determined that activity control significantly and positively predicts implementation of road constructions projects in Kilifi County (r = 0.909, P= 0.000< 0.01). The regression analysis showed that a unit improvement in activity control would significantly lead to an improvement in implementation of road construction projects in the county (β = 0.173, t =3.045, P = 0.003<0.05). Finally, the study found out that institutional capacity affects road projects implementation (r = 0.558, P=0. .003 < 0.01). It was also determined that institutional capacity has moderating influence on the relationship between time management and road project implementation (β = 0.185, t = 4.302, P=0.000 < 0.05).Unique contribution to theory, policy and practice: The study recommended that for effective time management during implementation of road construction projects, there should be stakeholder involvement as this will facilitate ideas and perspective. Stakeholder involvement in time management and planning, will better their correspondence, improve accuracy of information, increase credibility and acceptance findings and finally improve the quality road constructions projects in Kilifi County.

Purpose The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures. Design/methodology/approach The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays. Findings About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related). Research limitations/implications The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis. Practical implications The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana. Originality/value The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.

There are numerous participants involved in construction projects including the client or sponsor of the project, regulatory bodies, contractors, consultants, ward councilors, community who affect or become affected by the project. Stakeholders can affect the road construction positive or negatively. Stakeholder’s engagement is done to avoid unnecessary conflicts and controversies and to attain the desired successful implementation of the project. The paper aims to identify the impact of internal stakeholders on road construction project. Quantitative approach was adopted for this study. 100 questionnaires were distributed and 76 were collected and analyzed. The data was collected through primary and secondary sources. Factor analysis was conducted, Correlation matric coefficients has been conducted to ensure visibility of coefficients greater than 0.3 and Kaiser-Meyer-Olkim (KMO) and Barlett’s test were conducted. From the findings it transpired that late payment to service providers; failure to verify contractor qualification; Client knowledge to review design documentation; inadequate involvement during construction project, lack of understanding project feasibility. The participation of stakeholders encourages the public to share their knowledge with the regulatory authorities, fosters better-informed decisions and decreases likelihood of project failure. Early stakeholder’s involvement can add benefits of diffusing opposition to a project.

Delays in road construction projects due to various reasons are a major problem facing construction professionals. The incapability of finishing projects punctually and within a given budget is a persistent issue worldwide. This study aims to determine the ten principal causes of delay in road construction projects in 25 developing countries across the globe. The study involves two steps. First, the authors compiled information regarding the most frequent delays in a road construction project. Second, they analyzed the intensity of each cause of delay in these projects. Being more accurate in the methodology, given the nature of the information, the researchers used a quasi-meta-analysis for processing the data. Half (50%) of the countries have similar causes of delay, and likewise, 50% of the countries identified the top ten primary causes of delay in road construction projects based on the intensity results. This study uses the results of the intensity. According to the results of the homologation, the lack of experience of the construction manager, inadequate planning/scheduling, and influence on people’s land alongside the road construction project (expropriation for the construction of the project) have more significant impacts than frequent changes in the design (which was listed as the most frequent cause of delay).

Level Of Risk

The article considers the procedure for financing of the construction of regional roads on the basis of the life cycle contract. Under the existing procedure for financing road construction projects, the main burden at the stage of the implementation is experienced by the private partner, which can lead to the risk of non-fulfillment of obligations under the contract of the road project. To reduce the level of risk, it is proposed to use phased financing of the project by the state partner, especially before the commissioning of the facility.
